Original 1st printing 16&1/4 x 22&1/4" concert poster for the Grateful Dead appearing with Levon Helm and the Cate Brothers and Roy Buchanan at the Lewiston Fairgrounds in Lewiston, ME on 9/6/1980.

 Designer unknown (photo by Bob Seidemann), medium-thin flat index stock poster is in decent/used (B-) condition; there are tack holes in all four corners, along with a moderate to heavy amount of creasing/moisture wear and a series of tiny pin-prick mold spots scattered throughout the poster, a series of thin horizontal roll creases traversing the entire image area, a bit of edge creasing and other assorted little issues here and there... it's pretty obvious this example was subject to outdoor conditions and was very likely rescued from total destruction by an enthusiastic Deadhead. The paper and moisture issues have long since stabilized, and while not the most attractive GD poster on the planet, it still remains a fairly presentable example.

 Uncommon early-'80's regional New England Grateful Dead concert poster from a VERY fondly remembered show. Listen to a great-sounding audience tape HERE:
